Question

technician a says that a drive - by - wire refers to an engine that utilizes an electronically controlled throttle. technician b says that an electronically controlled throttle uses a position sensor on the accelerator pedal to calculate the drivers desired throttle position. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

• Technician A: Drive - by - wire systems do involve an electronically controlled throttle (instead of a mechanical linkage), so this statement is correct.
• Technician B: In an electronically controlled throttle system, the position sensor on the accelerator pedal is used to detect the driver's input (desired throttle position) and send this information to the engine control unit, so this statement is also correct.

Answer:

c. Both Technician A and Technician B
